n: a sudden and usually of short-duration increase in pressure. When pipe or casing is nm into a hole too rapidly, an increase in the hydrostatic pressure results, which may be great enough to create lost circulation.

n: a method of making up diamond bit.

n: a system of conducting regular checks and testing of equipment to permit replacement or repair of weakened or faulty parts before equipment failure results.

n: a unit that produces electricity from the chemical reaction of conductors of dissimilar metals through an electrolyte. In a primary cell, the chemical energy has its origin within the cell, and the chemical reaction is not reversible. Also called a voltaic cell. See dry cell, wet cell.

n: the first stage of oil production in which natural reservoir drives are used to recover oil, although some form of artificial lift may be required to exploit declining reservoir drives.

the amount of the reserves recovered by primary production, i.e., without injected fluid pressure support.

water, ranging from fresh to salty, produced with the hydrocarbons as a result of pressure drawdown and flow through the formation.

a vessel through which production passes and the multi-phase fluids are broken and separated.

n: (PI) the curve on a graph that results when the volume of a wells production is plotted against time. The curve is used to evaluate a wells perfonnance when it has single-phase flow.

n: a technique for simultaneously sampling gas or liquid at several points across the diameter of a pipe to identify the extent of stratification at a proposed location.

n: the seaward buildup of a beach, delta, or fan by nearshore deposition of sediments by a river, by waves, or by longshore currents.
